Abstract (en)
Broadband optical distribution system for a local optical fibre network in which the heterodyne or homodyne principles are used. So as to utilize the wavelength range available for transmission to the best possible extent, highly stabilised auxiliary oscillators (16-N) are included in the main exchange (1). On the request of a subscriber a given auxiliary frequency is transmitted to the subscriber. Said auxiliary oscillators can be utilized by several subscribers, the expenses resulting from the auxiliary oscillators being shared by several subscribers.
